Watering your plants with tea

1. What's really in your cup of tea?

Beyond its comforting taste, tea is an infusion of organic matter rich in elements valuable for the soil:

• Nitrogen (4.4%): This is the main fuel for leaf growth (much more present than in some liquid fertilizers!).
• Potassium & Phosphorus: Essential for root vigor and flowering.
• Tannic Acid: It slightly acidifies the soil, which helps some plants to better absorb nutrients.

In summary: It is a "gentle" fertilizer that nourishes the plant without risking burning the roots (unlike overdosed chemical fertilizers).

2. The golden rules of tea watering

Before emptying your teapot, here are some essential precautions:

✅ What's good:

• Black, Green or White Tea: It doesn't matter what color it is, as long as it's natural.
• Organic: To avoid adding pesticides to your plants' soil.
• Cold: ALWAYS wait until the tea is at room temperature. Boiling water will instantly kill your plants.

❌ What to avoid:

• Sugar: It attracts fruit flies and promotes mold. If your tea is sweetened, drink it!
• Milk: When it spoils, it gives off bad odors. Keep your "cloud of milk" to yourself.
• Commercially produced iced tea: Too much sugar and chemical preservatives. Avoid it.

3. How to proceed? (3 Methods)

Method A: The "Bottom of the Cup"

This is the opportunistic method. Have you let your tea cool down? Simply pour it at the base of the plant (onto the soil, not the leaves). It's an immediate hydration boost.

Method B: The Watering Can Infusion (Our favorite)

Don't throw away your used sachets! Soak them overnight in your watering can filled with water. The remaining nutrients will slowly release their nutrients.

The next day, remove the tea bags (compost them if they are paper without plastic) and water as usual. It's a kind of "light tea" ideal for regular use.

Method C: Burial

If you use loose leaf tea or 100% biodegradable tea bags (staple-free, plastic-free), you can bury the damp bag directly in the soil. As it decomposes, it will act as a slow-release fertilizer.

4. Which plants like tea? (Acid-loving plants)

Tea contains tannic acid, which lowers the soil pH (making it more acidic). This is fantastic for plants that prefer acidic or tropical soils, but less so for those that like limestone.

✅ The "Tea Team" (They love it):

• 🌿 Ferns
• 🌸 Orchids
• 🌺 Azaleas & Hydrangeas
• 🍅 Tomatoes (from the garden)
• 🌱 Philodendrons
• 🌵 Christmas Cactus

Friendly advice: Don't add tea every time you water. Once a month is a great frequency to boost your plants without upsetting the soil balance.

To your health (and to the health of your plants)!

Natural gardening is an exciting adventure. Recycling your tea bags is a simple little gesture that benefits your "inner jungle".
